IMPROVEMENT IN FOOT-STOVES.

Specification forming part of Letters Patent No. 4236!, dated April5,1864.

To all whom it may concern.-

Be it known that 1, JOHN THOMPSON, of Brooklyn, E. D., in the county ofKings and State ofNew York, have invented a new and Improved Warming-Panand I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a. part of this specification, in which- Figure 1represents a longitudinal vertical section of my invention. Fig. 2 is atransverse vertical section of the same, the line .10 m, Fig. 1,indicating the plane of section.

Similar letters of reference in both views indicate corresponding parts.

The invention consists in the application to a warming-pan of an airchamber, with perforated or solid sides, in such a manner that the feetor other parts of the body can be warmed without coming in directcontact with the surface of the pan.

The invention consists, also, in a warmingpan constructed in the shapeof a T, so that in placing the feet on the two horizontal wings of thepan the vertical wing extends up between the legs, and the beneficialeffect of the pan is extended over a larger portion of the body thanwith warming-pans of the usual construction.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it. 1

A represents a warmin g-pan. constructed of tin or any other suitablematerial,ronnd, oval, square, or in any desired form or shape. It ismade in the shape of the letter T, with two horizontal wings, a, and avertical wing, 11, and the vertical wing is provided with an opening 7(r mouth, 0, through which hot water can be introduced, and may beopened or closed by a screw-cap, d. The horizontal wings a are made witha flat bottom and rounded top, as clearly shown in Fig. 2 of thedrawings, and their top is covered by an air'chamber, 6, formed by aperforated piece of sheet-metal, f, which is supported by the archedstrips, 9 and a longitudinal strip, 9. The feet can thus be placed onthe surface of the pan and warmed without coming in direct contact withthe heated surface of the body of said pan, which is of particularadvantage when the pan is to be used in a bed where the bare feet areplaced on it. The upright wing 11 is surrounded by an air chamber, It,the sides of which are supported by strips 6, as shown in Fig. 1.. Thesides of this air-chamber may be solid, so as to emit less heat than theperforated sides of the air-chamber 0, because the legs with which itmay come in contact cannot stand the same degree of heat as the barefeet.

It is obvious that an air-chamber similar to those above described maybe applied to a warming-pan of any description, and I do not want toconfine myself, therefore, to a pan of the precise form shown in thedrawings. A T-shaped pan, however, has its peculiar ad; vantages,because its effect is not limited to the feet alone, but extends up tothe legs.

What I claim as new, and desire to secure by Letters Patent, isr l. AT-shaped warming-pan, a b, with or without air-chambers e h, as setforth.

2. The combination of the horizontal airchamber 6 and vertical airchamber h with the T-shaped reservoir on b, substantially as specified.

JOHN THOMPSON.
